II. Case Problem
Step 1: Find the demand unit function.
The data given in table form are plotted on a cc-place, and a freehand
straight line is fitted to the points, as shown on page 17-2. From the
chart we may read points (5.50, 4500) and (10, 0). Let p represent the
price and q units of the mechanical toy. Substituting in formula (2) of
Arithmetic (Linear) trend method, we have
=

and

q - 4500
0 - 4500
4.50(q
4500)

=
-4500(pp - 5.50
10 - 5.50 5.50),

q = Q(p) = -1000p + 10,000.
Note that Q is the unit demand function where price is the independent
and quantity the dependent variable.

Let C be such a function. Since fixed costs are expected to be P5000
- PESOS)
and variable P2.00 per toy,(PRICE
the cost
function by formula (1) of
Arithmetic (Linear) trend method is

C(q) = 2q + 5000.
On the basis of functions Q and C we can derive the sales revenue and
profit functions.
